information concerning the toxicity for zinc difluoride does not exist.
Instead, toxicological information on very soluble inorganic fluoride
(mainly sodium fluoride) substances and very soluble inorganic zinc
substances were extrapolated to zinc difluoride considering that
systemic effects mainly based on the concentrations of the Zn2+ and F-
ions, which are the key concern of zinc difluoride.
For read-across justification please
refer to IUCLID section 7 "toxicological information" - "additional
information" or to the report attached under IUCLID "0 category".
Sodium fluoride tested negative (i.e.
not sensitising) in sensitisation studies according to Buehler (EPA OPP
81-6). Furthermore, there are no indications that a zinc substance
causes skin sensitization in a guinea pig maximization test.
Positive human experience with zinc
difluoride has not been reported. Based on read-across (see attachment
on assessment entity), it is assumed that zinc difluoride does not
possess a skin sensitisation potential.
difluoride does not have a skin sensitisation potential and therefore
must not be classified and labelled according to Regulation (EC)
1272/2008 and subsequent adaptations.
